Borussia Dortmund have refused to deny reports that Chelsea starlet Kevin De Bruyne has signed a five year deal with the Bundesliga club.

German newspaper Bild have reported that De Bruyne, who is currently on a season long loan with Werder Bremen, has agreed a deal with the Champions League finalists, with a deal worth €15m close to being agreed between them and the Blues.

The Belgian international has yet to play for Chelsea since officially moving to Stamford Bridge in the summer of last year, but has garnered the attention of a host of Bundesliga clubs, a league where the 21-year-old has established himself as one of its brightest talents.

When quizzed on the reports of a contract agreement between De Bruyne and Dortmund, the club's general manager Michael Zorc remained coy on the issue.

"I am not going to either confirm or deny this agreement," the Dortmund official told Bild. "Kevin De Bruyne is under contract with Chelsea FC, he is a good player currently on loan at Werder Bremen."

The highly rated De Bruyne has been at the centre of a compelling tug of war between three Bundesliga sides, Dortmund, Werder Bremen and Bayer Leverkusen. After a terrific campaign where the young Belgian has struck eight goals and laid on another nine for his teammates, Bremen are desperate to make their loan deal for the Belgian a permanent one.

The issue of Andre Schurrle's future has further complicated matters. Bayer Leverkusen's prized asset has been heavily linked with a £20m move to Chelsea in recent months, but the conclusion of a deal would have seemed to rest on De Bruyne moving in the other direction, with Leverkusen keen to secure a replacement before parting with German international Schurrle.

But the interest from Champions League finalists Dortmund may be the deciding factor. Jurgen Klopp's side were dealt a heavily blow with the news that their own prized attacking midfielder Mario Goetze will join Bayern Munich this summer, after the Bavarian giants met his release clause. The imminent move has left the club looking for a direct replacement, with De Bruyne seemingly fitting the bill.

It would appear that the Chelsea loanee would jump at the chance to join Klopp's side. "Dortmund? That would fit me," the youngster said last week. "I am keeping tabs on what they have been doing.

"They have performed admirably in the Champions League, just like Bayern. We will see what happens."

In an added twist, reports suggesting Chelsea could use the Belgian as a makeweight in a deal for Dortmund striker Robert Lewandowski suggests a deal with Dortmund could be close to coming to fruition.
